Grandmother beyond halfway point in Cuba-Fla. swim
Cuba Swimming to Florida
British-Australian swimmer Penny Palfrey adjusts her cap in preparation for her bid to complete a record swim from Cuba to Florida as her husband Chris stands by, in Havana, Cuba, Friday, June 29, 2012. Palfrey aims to be the first woman to swim the Straits of Florida without the aid of a shark cage. Instead she's relying on equipment that surrounds her with an electrical field to deter the predators. (AP Photo/Ramon Espinosa)
